SPECIFICATION forming part of Letters' Patent No. 520,366, dated. May 22, 1 894. Application filed March 17,1893. Renewed April?, 1894. Serial No. 506,776- (No model.)

.To all whom t may concern.-

Beit known that JAMES M. LnAvnR, a subject ofthe Queen of England, residing at Bay City, in the county of Bay and State of Michigan, have invented a new and useful Corrugated Packing, of which the following is a specification.

' This invention relates to corrugated packing, and has for its objects togposition the cor` rugations thereof diagonally in order to make the samemore resilient and stronger, and to prevent a jar or force of a blow externally applied to apacking-case or other device wherein the improved form of packing is employed from being concentrated in one line eitherin a vertical or horizontal direction, and to disseminate or detract the force of the jar, shock.

or blow crosswise of the obj ect resting against the packing.

With these and other objects in View the invention consists of the construction and arrangement of the parts thereof as will be hereinafter more fully described and claimed.

' In the drawings: Figure l is'a perspective View of two layers or thicknesses of packing constructed and arranged in accordance with,

the invention. Fig. 2 is a'sectional view on the line :v -'4.13, Fig. l. Fig. 3 isa view similar to Fig. 2, showing'three layers in the packing. Fig. 4 is a detail perspective view of a slight modification of construction and arrangement of the corrugations.

corrugations are in like manner arranged di-` agonally. In the form of the device as shown in Figs. 1, 2, and 3 the corrugated strips or pieces 1 and 2 are placed back to back, or superposed, in such manner that the corrugations 3 thereof will extend in oppositediagonal directions, thereby increasing the number of points of contact at the places where the several corrugations cross or intersect each other. This form of packing is very'strong and resilient, and the shock or said corrugations will not return to their nor-v mal condition.

By the construction herein set forth,'if the material is properly selected, the diagonal corrugations will be more apt to resume their normal shape because they will not breakv but will spring away under pressure and again resume their proper form. It will be also understood thaty the packing herein set forth can be formed into partitions adapted to be set up in any suitable manner.

The arrangement of the diagonal corrugations having their lines of highest parts spaced the same distance apart on any given square provides for a material increase in the amount of cushion for the bottle or other breakable article surrounded by the packing. The variation in direction of the corrugation on the diagonal plan aords abetter support to the bottle or other breakable article and protects the same against concussions, the shock being distributed in a glancing direction on either side, whereas in aperpendicular or horizontal arrangement the corrugations bear upon a greater surface and will be more apt to affect a weak spot or defect in the bottle, while the diagonal arrangement will not cause so direct a bearingon as great a surface, because in any place Where the bottle or other article may touch the packing thelines are always Varying in length and direction. The most important advantage of the construction, however, is the increased number of contact points between the sheets or layers with the self-'evident increase in the strength off' the packing, and as shown, two or more sheets or layers maybe employed and the corrugations may be varied in form, though those shown are preferred.

In Fig. 4 a slight modification in construetion `is shown wherein the coi-rugations in In flat surfaces, or where cor-4 2A r '520,366I

Y. each layer extend diagonally alternately in opposite directions, and meeting each other at an angle at the points of intersection and thereby provide' for irregularly breaking up creased number of contact points is still pre served as in the previously described form,

With the additional advantage in this inf stance of further increasing the strength of the packing. l

.Changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

`Having described `the invention, what is` claimed as new is- A packing material comprising two or more superposed pieces of corrugated paper or like substance united, the corrugations of each piece ot' paper 'being arranged diagonallyand n extending at reverse angles on opposite sides of the packing material to secure the greatest possible number of contact points for the .superposed pieces, and to provide for distributing any shock imparted to the article,

placed on the packing, ,in a glancingvdirec` tion on either side, substantially as set forth. In testimony that I claim the foregoing as `my own I have hereto axed my signaturein the presence of two v vitnesses.

JAMES M. LEAVER.
